h2exp10

Applicability

Function Usage

Obtains the value of 10 raised to the power of each element of x with a given x.

Prototype

1

inline half2 h2exp10(half2 x)

1

inline bfloat16x2_t h2exp10(bfloat16x2_t x)

Parameters

Returns

The value of 10 raised to the power of each element of the input.

• If the input element is inf, the return value is inf.
• If the input element is -inf, the return value is 0.
• If the input element is nan, the return value is nan.

Restrictions

For SIMT programming, this API is not supported.
